Question

how many pieces of length 2/7 metres can be cut from a roll of ribbon of length 113 metres? how much ribbon remains?

Answer 1

$113 \div \frac{2}{7} =113 \times \frac{7}{2} = 791 \div 2 = 395.5 = it \: means \: 395 \: pieces \: and \: \: \\ 0.5m \:rebbon \: remain \:$

Answer 2

395 pieces can be cut and 1/7 meter ribbon remains.
$113m \: will \: have \: 113 \div \frac{2}{7 } = 395.5 \: pieces \: but \: half \: the \: piece \: is \: of \: \frac{2}{7} m \: hence \: \\ remaining \: length = .5 \times \frac{2}{7} = \frac{1}{7} meter$
